There's a big, wordy, angry and detailed review of Bethesda's newest creation over at ComputerGames.ro. Here's a snippet:

Maybe I’m overanalyzing here, but in the first two games(emphasis mine - Elwro) we had the perfect picture of a group of grotesque individuals who did their best to survive, while Fallout 3 brings about a massive equalitarian movement on their part. I don’t know about others, but a couple of retorts made me see the whole thing as a tad ridiculous. Obviously, we couldn’t have the Super Mutants excluded from this little party. So they’re back, stronger and more senile, being created in a Vault (surprise!!!).

Another major stray away from the concept of the original series is represented by the population’s make-up – the Capital Wasteland has a very high amount of mobs, creeps, whatever you wanna call them. Way too many compared to the characters you can actually interact with using something else than, as a character in-game remarks at one point, “shotgun diplomacy”.

But we’ve got some new groups as well – a gang of cannibals scraping the subway lines in an underground complex named after our very own Mereşti, a thriving community taking shelter on a beached aircraft carrier and even some religious fanatics sounding like any Sunday Scientologist, mixed with some principles we normally learn in 6th grade Physics class.

This is all true, but remember that Fallout 2 also included things like Hubologists. Compared to Fallout 1, yes, Fallout 3 does look silly sometimes.
